592536 - xulPanel is null error when show/hide methods are called

Status: RESOLVED WORKSFORME

(Add-on SDK Graveyard :: General, defect)

Description

[Daniel Buchner [:dbuc]]

When I show and hide a panel instance many times in a short period the panel eventually stops displaying content and creates empty duplicate panels without developer invocation.

Error: xulPanel is null

In restructuring the MailPing example for the upcoming blog post to work around this issue, I took an onClick approach to the showing of the panel and was able to replicate the error.

There is less of a chance of it occurring with click to hide/show (you have to click twice in a quick period) but it is does bork all panel functionality of any particular add-on for the entire session if it occurs. For this reason I believe this is a P1 bug, thoughts?

The Add-on SDK is no longer a Mozilla Labs experiment and has become a big enough project to warrant its own Bugzilla product, so the "Add-on SDK" product has been created for it, and I am moving its bugs to that product.

To filter bugmail related to this change, filter on the word "looptid".

Daniel: can you still reproduce this problem?

I will try to replicate it again, it has been a while since I last tested that flow, so perhaps it has been fixed. Will let you know what I find.

I can't reproduce the problem, so resolving worksforme, but please reopen if you can!
